Fetching Values from JSON Arrays in MySQL: A Laravel Guide

Managing data in modern web applications often involves interacting with complex data structures like JSON. In this guide, we’ll tackle a common challenge faced by developers: fetching values from a JSON array in MySQL using Laravel. This guide will walk you through the specifics of the problem and provide a clear solution, ensuring your queries work as intended.

The Challenge

Let’s consider a scenario where you have a table named data that contains a JSON array in one of its columns (named number). Here’s a simplified view of the table:

However, this query might not yield the desired results. So, how do you effectively search through a JSON array in this case?

The Solution

To successfully fetch the desired records, you’ll need to ensure that the JSON array values are stored as strings. Here’s how you can modify your number field in the data table:

Step 1: Update the Data Structure

Change the values in the number column to string format. Here’s what your updated table will look like:
